Waiora Clarity II + Waimana UV 33W Bundle - Whole House Filtration & UV Treatment NZ

Waiora Clarity II + Waimana UV 33W Bundle – Whole House Filtration and UV Treatment

Safe drinking water from a tank or bore supply needs two things working in sequence: sediment is removed first, then biological contamination is treated. This bundle pairs the Waiora Clarity II two-stage filter system with the Waimana UV 33W unit to cover both, giving smaller New Zealand homes on tank or rainwater a complete whole-house treatment setup without piecing it together separately.

The Clarity II clears the water before it ever reaches the UV chamber. That sequence is not optional, UV treatment loses effectiveness if sediment is still present in the water, as particles shield micro-organisms from the UV light. Running filtration first is what makes the UV work.

The Waimana UV unit runs on a flow-activated design. The lamp switches on when water moves through and off when it stops. No power running between uses, no water sitting in a heated chamber, and a lamp that is only working when it actually needs to be. Both units ship separately and are installed in line, with the Clarity II upstream and the UV unit as the final stage before water enters the home.

What Makes This Bundle Work

• Flow-activated UV lamp reduces power consumption and prevents heat build-up in the chamber between uses
• Two-stage sediment removal prepares water for UV treatment, which is essential for the UV to be effective
• Biological treatment without chemicals, dosing, or additives
• Stage 1 polypleated cartridge is cleanable and reusable between replacements
• Covers the full treatment sequence in one purchase rather than sourcing components separately
• Both units carry a 3-year warranty
• Standard 25mm BSP connections throughout for straightforward installation

How the System Works Together

Stage 1: Coarse Sediment (Clarity II)

The 20 micron polypleated filter takes the first pass, pulling out larger particles, silt, and organic debris from your supply. This cartridge is cleanable and reusable between replacements, which helps extend its working life.

Stage 2: Fine Sediment (Clarity II)

The 1 micron polyspun filter removes the finer particles that pass through Stage 1, and physically blocks Giardia cysts at the same time. Water leaving this stage is clear and ready for UV treatment.

Stage 3: UV Treatment (Waimana UV 33W)

Water passes through the stainless steel UV chamber where the 33W lamp delivers a dose of 30 mJ/cm2, treating it against bacteria, viruses, and micro-organisms. The integrated flow switch activates the lamp when water is moving and cuts it off when demand stops.

The order matters. Sediment filtration before UV is not just recommended, it is what makes the UV treatment reliable. Clear water in the chamber means the UV light reaches everything it needs to.

Good Fit For

Smaller NZ homes on a tank or rainwater supply. Properties wanting a complete filtration and UV treatment setup in one purchase, households where sediment and biological contamination are both a concern, and anyone who wants chemical-free water treatment with minimal ongoing maintenance

Not Ideal For

Large households or high-demand properties needing flow rates above 30 L/min. Browse our rainwater filtration with UV range for higher capacity options. Bore water without prior testing. Bore supply quality varies considerably from site to site, and additional treatment stages may be needed. If you are unsure, a professional water test is the right starting point.

FAQs

1. Why do I need both filtration and UV?

They do different jobs. Filtration removes sediment and particles. UV destroys bacteria, viruses, and microorganisms. Neither is fully effective without the other for tank or bore water.

2. Why does the order of installation matter?

UV light cannot penetrate turbid water effectively. Sediment in the chamber shields micro-organisms from treatment. The Clarity II ensures clear water arrives at the UV unit every time.

3. Does the 1 micron filter remove Giardia?

Yes. Giardia cysts are typically 8 to 12 microns in size, so the 1 micron polyspun filter physically blocks them. The UV stage adds a further layer of protection.

4. Is this bundle suitable for bore water?

It can be, but bore water varies considerably between sites. We recommend testing before ordering to confirm that this configuration suits your supply. Get in touch, and we can help.

5. Do both units need to be installed at the same time?

No, they can be installed separately. The Clarity II goes upstream, and the UV unit is always the last stage before water enters the home.

6. Do I need a plumber?

Yes, a licensed plumber is recommended for both units. Standard 25mm BSP fittings throughout, and the UV unit plugs into a standard 240V outlet.

7. What does the warranty cover?

Both units carry a 3-year manufacturer's warranty. Filter cartridges and the UV lamp are consumables and are not covered under warranty.
